In this sermon A Light To The Gentiles,  we learn missionaries must have great faith and large amounts of determination. They also must have a stock of dedication, the ability to pray and press through opposition. Missionaries must have the ability to endure physical, emotional, and spiritual persecution. Missionaries have to live under some of the most challenging of circumstances of all people. Not only do they have to forego many of the American amenities that we have, they are on the very front-line of spiritual attack in the places they are trying to establish churches and make converts.
